I would say, speaking as someone who is not yet a part of the Church, that no, you are not a Christian. You are, however, definitely a very potential Christian. I encourage you to start attending an Orthodox Church near you.
I think what you are saying is within the realm of possible Orthodox views, so please don't misunderstand what I'm going to say. Nonetheless, I'm not sure that defining the term Christian as narrowly as you are doing (?) is helpful. Unlike baptism, I don't think the usage of the term Christian is a dogmatic issue, but rather one of labels and identification, and I don't wonder if we shouldn't use a bit of economia in this area. How exactly would you define or describe who qualifies as a Christian? Someone who is part of the Eastern Orthodox Church? Oriental Orthodox Church? Roman Catholic Church? Thoughts?
In my opinion (and keep in mind this is merely my opinion, I am not trying to speak for anyone or anything - let alone the Holy Orthodox Church of which I am not even a part), the very word Christian implies you are a member of the One, Holy, Catholic, and Apostolic Church. As such, it should be a person received into the Orthodox Church, either through baptism and then chrismation in the Church, or through those claiming to be the Church baptising such a person and the Orthodox Church giving the baptism grace by christmating the person and receiving them. The person should also believe the dogmas of the Church, and should be in good standing (not be excommunicated). I think that when you let anyone claim the word Christian, and don't say that they are not really a Christian (at least if they ask you, if they don't ask yo I can accept and myself would probably not, correct them our of politeness) then you tacitly accept non-Orthodox Churches of bein - or at least being part of - the One Holy Catholic and Apostolic Church. I think, in a way, it would be the same as saying that you are an American, by that most people assume you mean an American citizen, not just someone who likes America. As such, I would say taht no, the Roman Catholic Church does not get to call itself Christian, nor those inside of it (of course, I obviously mean they can call themselves such, but I do not accept it as truth). Would I agree that someone in the OO Church is a Christian, I am not sure. I have thought from time to time about it, because I do believe that the EO and OO share one faith, but are they really part of the One Holy Catholic and Apostolic Church? I think they are somewhere between being part of the Church, and being schismatics. Which they are closer to, I am not sure.
Anyways, this could simply be a holdover from when I used to be an evangelical protestant and regularly tell people how Roman Catholics were not Christians.
